Spoon FeedLow and high extremes of prehospital vital signs were associated with higher rates of hospitalization and in-hospital mortality; however, there was not statistically significant improvement in their model when using age adjusted vital signs.
What were those vitals again?Researchers used a national database of EMS encounters within the United States to derive centiles of vital signs for adults; an additional database was used to validate this sample. Sets of vital signs were both age adjusted, and non-age adjusted to determine if different cutoffs would prove more reliable in predicting in hospital outcomes. They extracted heart rate (HR), respiratory rate (RR), and systolic blood pressure (SBP) for the patient encounters. When there were multiple sets of vital signs obtained during an encounter, they selected the first set documented. Vital signs that had a high chance of being erroneous or not compatible with life were excluded (ex. RR >120 or <1). All EMS encounters with a documented age >18 years that were transferred via a BLS or ALS crew were included. The data set (from 2018) was 13+ million encounters of which 2.5 million had in-hospital data later available.
